Yes-in-deedy! Undrivable barely describes it! Of course, Reboot's Sebring is itself almost comically bumpy (according to no less a source than the esteemed LilSki), but even so, the crsh 911 is beyond the pale. Attached is my attempt to curb the kinetic chaos: raise the ride height and soften all the verticals (spring weights, jounce settings) and stiffen the bars a bit to compensate. And hold onto your hat!
Edit: Nope! I wuz wrong. Attached is a revised Reboot Sebring setup for the crsh 911. Even so, the setup data points are suspect. For instance: no matter how much you fiddle with the cambers, the tire temps across the tread never change by more than a couple of degrees (and you can't dial in any negative toe up front). That's just plain wrong. Back to the old drawing board....
